Title: Regeneration of ferric chloride solution
Inventor: KAJIYAMA TAKAMORI
IPC: C23F1/46
Filed: 1987-12-23
Abstract: PURPOSE:To enhance Ni-removal efficiency by combining the reduction process using metallic iron and the Ni-removal process using iron powder and by grinding treatment of an iron powder slurry used to retain or enhance the activity when ferric chloride etching waste liquor containing a large amount of Ni is to be treated. CONSTITUTION:A nickel-contg. metal plate is etched with a ferric chloride solution and the resultant ferric chloride etching waste liquor containing a large amount of nickel is incorporated with metallic iron to reduce the remaining ferric chloride into ferrous chloride. Thence, the resulting solution thus reduced is incorporated with iron powder to separate nickel out along with grinding treatment of the solid product from the nickel-removal process to retain or enhance the activity of the iron powder, which is reused another nickel-removal process. The nickel separated out is then recovered and the resultant nickel-removed solution is oxidized with an oxidizing agent (e.g., chlorine) to regenerate ferric chloride, which is circulated to the etching process to be reused.

Title: Light source for endoscope
Inventor: TAKADA SHIN
IPC: A61B1/06
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent an accident and failure caused by temperature elevation by lowering of the rotation number of a cooling fan for a light source lamp from occurring by detecting the rotation number of the cooling fan to cool down the light source lamp and putting off the light source lamp if the rotation number is lower than or equal to a prescribed one. SOLUTION: A rotation number sensor 33 to detect the rotation number of a cooling fan 32 for exhaust is mounted on a box body 31 immediately outside the cooling fan 32 for exhaust. Since the rotation number sensor 33 is a photoelectric element to change the intensity of light coming out from the box body 30 every time a blade of the rotating cooling fan 32 for exhaust crosses in front of the rotation number sensor 33, the rotation number of the cooling fan 32 for exhaust is detected thereby. When the rotation number detected by the rotation number sensor 32 is lower than or equal to a prescribed rotation number, a light source lamp 11 is put off by a control part. Thereby, an accident and failure caused by temperature elevation by rotation number lowering of the cooling fan can be prevented from occurring.

Title: Manufacture of semiconductor device
Inventor: MORIYA NAOHIRO
IPC: H01L21/321
Filed: 1988-12-27
Abstract: PURPOSE:To improve mounting stability by making a semiconductor metal to be spherical and the upper part to be flat and smooth, reducing fluctuation of height between bump type electrodes, and widening the contact area between a solder and a mounting board. CONSTITUTION:A bump type electrode consists of a diffusion barrier metal 2, a spacer metal 3, and a solder 4 which are placed on an electrode pad of an integrated circuit substrate 1. Since the spacer metal 3 and the solder 4 are formed by plating, it becomes like a mushroom. In this shape, the height of the bump type electrode is low so that the solder is fused by a solder reflow treatment and the surface tension achieves a spherical shape. Then, by applying mechanical pressure to the upper part of the pump type electrode from upper direction, a flat and smooth shape can be formed. Solder should not be collapsed excessively, thus leading to loss of solder height, and over-excessive load should not be applied to the electrode pad at the joint of the bump type electrode. Apply approximately 7 to 8 gram weight per bump type electrode.
